Ever since Apple has been weirdly overprotective over their repair system that usually goes on the Apple Store. However, an anonymous tipster who used to work at the Apple Store took a photo of Apple's iPhone Calibration Machine, a device that monopolizes certain types of iPhone screen replacement.

Motherboard reported that the Apple has been started using iPhone Calibration Machine after the release of the iPhone 5S. The anonymous tipster also added that the machine could be immensely very important t if the company decides to integrate fingerprint sensor into the screen of the next iPhone.

And that is a big deal because it is one of the components that the other repair stores have been unable to crack the secrets of the machine so far. The iPhone Calibration Machine is generally a testbed that permits the repaired iPhones to be calibrated to a factory standard before returning it to the owners.

Moreover, BGR added that it took a series of tests to calibrate the display, touchscreen, camera, and the internal sensors. There were different molds for different iPhone models before going into the machine, and it would take 30 minutes to calibrate. Apple has a proprietary technology to test the iPhone repair before giving it back to the owners.

The iPhone Calibration Machine will also allow a new Touch ID button to be paired with the old device. The machine is actually dependent to an iMac, which the phone is connected to an internal Apple server and permits the sensor to recalibrated. With this, there is no independent repair shop can do, as it allowed only Apple that can fix the broken screens without swapping the old Touch ID buttons from the old screen

An independent smartphone repair CEO Justin Carroll said that it would be great for them if Apple will do the open-sourced its diagnostic modes to the other people. He added that it would make their lives easier, and it is not just a realistic one but it also monopolizes the aspect of the business that is rarely good.
